There was no immediate word on whether the FBI had put a trace on the Hamburglar's IP address, but at least one journalist drew a link between Monday's hack and a group that infiltrated Paris Hilton's cell phone back in 2004.

That hack by an alleged member of the self-proclaimed "Defonic Team Screen Name Club" led to the contents of her address book being posted online, including the private phone numbers of many celebs.

A Burger King spokesman told The Associated Press that the company asked Twitter administrators to suspend the account. According to the AP, Burger King planned to post a statement on Facebook later Monday to apologize, especially for the offensive posts, and hoped to have the Twitter account back up soon.

For their part, McDonald's was a good sport about the ordeal, tweeting out the following message Monday afternoon: "We empathize with our @BurgerKing counterparts. Rest assured, we had nothing to do with the hacking."
